Phone Shark Masq, new app & developer, feedback welcome.

Just finished creating my first app for Android called Shark Mask. It's a utility that lets you run DNSMasq on your phone to serve as a dns caching server, which lets you select DNS servers, block unwanted address and select a DNS server per address. I've tested that last part to use pandora outside of the States via Tunlr and it worked great. The works on phones and tablets and has binaries for DNSMasq to work on intel, mips and arm based devices. The only major requirement is the device be rooted.

Looking for other ideas for the app and places to promote it on. I've got it on Google Play so far and looking at placing it on Amazon as well.

Here's the Google Play Link,

Thanks in advance
